A thermal insulation device for subway passages

Abstract

The invention discloses a warm insulation device for a subway passage, comprising a subway passage, a blower is installed on the top of one side of the subway passage, and the air outlet end of the blower is connected with an air outlet pipe extending along the top of the subway passage. The lower end of the air outlet pipe is equidistantly provided with a plurality of air outlets, a solenoid valve is installed at the corner of the end of the air outlet pipe, and a fan blade is arranged inside the end of the air outlet pipe, and the fan blade is connected with a connecting shaft. The ground of the subway channel is provided with a drainage groove, the bottom of the drainage groove is connected with a drainage pipe, the notch of the drainage groove is covered with a spacer, the inner wall of the drainage groove is horizontally provided with a mounting groove, and the connecting shaft The lower end of the lower end extends into the installation groove, and the inner wall of the installation groove is rotatably connected with a reciprocating lead screw. The invention has a reasonable structure, can form an air curtain to isolate warm gas, reduce the electric energy required for air-conditioning and cooling, and can timely absorb accumulated water on the screen.

Description

technical field [0001] The invention relates to the technical field of subway stations, in particular to a warm insulation device for subway passages. Background technique [0002] A subway station is a place where railway trains stop for the urban rail transit system (referred to as the urban rail system) to carry goods or allow passengers to ride. A subway station usually has multiple entrances and exits to facilitate pedestrians without crossing the road Entering the station, for the convenience of passengers, elevators, stairs and elevators are generally installed between the lobby and the platform. The subway stations with a large span may even have electric flat walkways, which are generally installed for the comfort of passengers. Air Conditioning System. [0003] At present, in the hot summer, the air conditioner is usually turned on in the subway station. People take the elevator to enter the subway passage through the subway entrance. Since the air-conditioning ai...

Problems solved by technology

[0003] At present, in the hot summer, the air conditioner is usually turned on in the subway station. People take the elevator to enter the subway passage through the subway entrance. Since the air-conditioning air is generated from the hall at the end of the subway passage, people walk to the subway passage and the subway passage after going down to the passage. At the junction of the hall, you can feel the obvious temperature difference, and the hot air in the subway passage will continuously enter the hall, so you need to increase the air output of the air conditioner to maintain a certain temperature, resulting in a waste of electric energy; and when it is raining At the same time, there is often a lot of rainwater remaining on the ground of the subway passage, which cannot be drained away in time.
